Abstract
According to the invention, the coil of a magnet coil arrangement has a coil body which comprises a winding (14) and is extruded with plastic (17). A plug-in base with contact connectors is formed on the coil, wherein one of the connectors is used for connection of the grounding conductor (18). A metallic housing is placed over the coil. Connection of said metallic housing to the contact connector associated to the grounding conductor is achieved by means of a connection element which is guided through a recess of the plug-in base. A sealing element (42) disposed between the connection element and the recess prevents penetration of a fluid from a region between the metallic housing and the coil, into the region where a connector is connected to the contact connectors. In order to improve the electrical connection between the contact connector associated to the grounding conductor and the metallic housing, for a connection element (31) which is threaded in the metallic housing, a cylindrical metallic part is placed between the contact connector and the metallic housing. A respective sealing element (41, 42) is placed between the connection element and the metallic cylindrical part as well as between said part and the recess of the plug-in base. Such magnet coil arrangements are used in electromechanically-controlled hydraulic valves in which metallic parts accessible from outside must be connected to a grounding conductor.
Description
- The invention relates to a magnet coil arrangement having an encapsulated coil, which comprises a coil former that is provided with a winding and is extrusion coated with plastic, and having a metal housing which is pushed over the encapsulated coil and surrounds it, as claimed in the precharacterizing clause of claim1.
- A magnet coil arrangement of this type is known from DE 198 54 100 A1. A coil former which is provided with a winding is extrusion coated with plastic and forms an encapsulated coil. A plug cap is integrally formed on the encapsulated coil. Contact lugs are held in the plug cap, two of which are connected to the ends of the winding, while a third is associated with the protective ground conductor connection. The electrical connection is made via a connecting plug which is plugged onto the contact lugs. The housing of the connecting plug provides an external seal for the contact area which is formed by it and the plug cap. A metal housing is pushed over the encapsulated coil. In the process, the metal housing engages in a recess between the plug cap and the outer surface of the encapsulated coil. The plug cap is provided with a recess, through which a connecting element is passed. The connecting element produces the electrical contact between the metal housing and the contact lug that is associated with the protective ground conductor connection. A sealing element is arranged between the connecting element and the recess in the plug cap and rests both on the circumferential surface of the connecting element and on the inner surface of the recess in the plug cap, forming a seal. The sealing element prevents moisture which has penetrated in between the outer surface of the encapsulated coil and the metal housing from being able to reach the connection area. In one exemplary embodiment, the connecting element is in the form of a screw, which is passed through a hole in the contact lug that is associated with the protective ground conductor connection, and whose thread is screwed into the metal housing. In this case, the contact lug is clamped in between the head of the screw and the plug cap. Even if the screw is tightened during assembly with a torque which is sufficient to make electrical contact, it is impossible to preclude the possibility of the plastic of the plug cap changing its characteristics over the course of time, in particular shrinking or changing its elasticity. This can lead to the contact resistance between the contact lug and the screw head becoming greater, such that an adequate electrical contact is no longer provided. There is no such risk when the connecting element—as in another exemplary embodiment in DE 198 54 100 A1—is connected to the contact lug and the metal housing via a metallic push connection in each case. In this situation, any change in the characteristics of the plastic that is used for the plug cap has no disadvantageous influence on the electrical contact resistance between the contact lug and the connecting element, or between this and the metal housing.
- The invention is based on the object of ensuring a permanent electrical contact between the contact lug and the metal housing in a magnet coil arrangement of the type mentioned initially, even when the contact lug that is associated with the protective ground conductor connection is connected to the metal housing by means of a screw connection.
- This object is achieved by the features characterized in claim1. A component is connected by a force fit to the tubular metal part which is arranged between the contact lug and the metal housing, and this component ensures that a reliable electrical contact is made in the long term, irrespective of the material characteristics of the plastic that is used for the plug cap.
- Advantageous developments of the invention are characterized in the dependent claims. These relate to the design configuration of the connecting element between the contact lug and the metal housing, including the electrically conductive connection between the contact lug, the connecting element and the metal housing, as well as to the configuration of the sealing elements which are arranged between the connecting element and the cutout in the plug cap.
- The invention will be explained in more detail in the following text, with its further details, with reference to exemplary embodiments which are illustrated in the drawings, in which:
- FIG. 1 shows the mechanical configuration of the magnet coil arrangement according to the invention, in the form of an exploded drawing,
- FIG. 2 shows a section through a detail of the magnet coil arrangement illustrated in FIG. 1, on an enlarged scale, in which a tubular metal part is arranged between the contact lug for the protective ground conductor connection and the metal housing, and
- FIG. 3 shows a section through a detail of the magnet coil arrangement illustrated in FIG. 1, on an enlarged scale, in which the contact lug and the tubular metal part are formed integrally.
- Identical components are provided with the same reference symbols.
- FIG. 1 shows the mechanical configuration of a magnet coil arrangement according to the invention, in the form of an exploded drawing. The magnet coil arrangement comprises an
encapsulated coil 10 and ametal housing 11, which is formed from acoil pot 12 and apole plate 13. Theencapsulated coil 10 comprises a coil former 15, which is provided with a winding 14, is extrusion-coated withplastic 16, and on which aplug cap 17 which is provided with three contact lugs is integrally formed. The cross section of the contact lugs is rectangular. Only the contact lugs 18 and 19, of the three contact lugs, can be seen in FIG. 1. Thecontact lug 18 is associated with the protective ground conductor connection. Thecontact lug 19 is connected to one of the two winding ends of thecoil 14. The contact lug which is connected to the other winding end of thecoil 14 is concealed by thecontact lug 19. The electrical conductors are connected to the magnet coil arrangement via a connecting plug, whose housing is illustrated schematically in FIG. 1 and is provided with thereference symbol 20. Thehousing 20 of the connecting plug provides an external seal for thecontact area 21 that is formed by theplug cap 17 and thehousing 20. Arecess 23 is provided between theplug cap 17 and theouter surface 22 of theencapsulated coil 10. Theplug cap 17 is held on theencapsulated coil 10 via aweb 24 and afurther web 25, which extends in the longitudinal direction of theencapsulated coil 10 and bounds therecess 23. - The
coil pot 12 is provided with arecess 26, in the form of a slot, and with ahole 27. When theencapsulated coil 10 is pushed into thecoil pot 12 during the assembly of the magnet coil arrangement, therecess 26 which is in the form of a slot clasps theweb 25 which bounds therecess 23 at the sides. In the process, the wall of thecoil pot 12 is pushed into therecess 23 until thehole 27 is located under acutout 28 that is illustrated in FIGS. 2 and 3. The magnet coil arrangement is closed by pushing thepole plate 13 into thecoil pot 12. Thecoil pot 12 and thepole plate 13 form themetal housing 11, which surrounds theencapsulated coil 10. - FIG. 2 shows a section through a detail of the magnet coil arrangement illustrated in FIG. 1, on an enlarged scale. This illustration shows the third contact lug, which is concealed by the
contact lug 19 in FIG. 1 and is connected to the second end of the winding 14. This contact lug is provided with thereference symbol 29. Ascrew 31 made of electrically conductive material is used as a connecting element for thecontact lug 18 and thecoil pot 12. Thescrew 31 is provided with ahead 32 and with athread 33 at the end remote from thehead 32. Thehead 32 is provided with aslot 34 for holding the blade of a screwdriver. A different geometry for holding a mounting tool can also be used instead of aslot 34. Atubular metal part 36 is arranged between thecontact lug 18 and thecoil pot 12, and is located within thecutout 28 in theplug cap 17. One end surface of thetubular metal part 36 rests on thecontact lug 18, and the other end surface rests on thecoil pot 12. Thescrew 31 is passed through ahole 35 in thecontact lug 13 and through thetubular metal part 36. Thehole 27, which is illustrated in FIG. 1, is provided with athread 37, into which thethread 33 on thescrew 31 is screwed. Thecontact lug 18 and thetubular metal part 36 are clamped in between thehead 32 of thescrew 31 and thecoil pot 12. Thetubular metal part 36 has essentially the same mechanical characteristics as thescrew 31, and is primarily used as a spacer. The electric current which flows between thecontact lug 18 and thecoil pot 12 is split between two parallel paths, one of which passes via thescrew 31, while the other passes via thetubular metal part 36. - The
screw 31 is provided with anannular groove 40 in the area between thehead 32 and thethread 33. Asealing ring 41 is held in theannular groove 40, and is used as a sealing element between thescrew 31 and the inner wall of thetubular metal part 36. Afurther sealing ring 42 is used as a sealing element between the outer wall of thetubular metal part 36 and the inner wall of thecutout 28 in theplug cap 17. Thecutout 28 has a circular cross section, particularly in the area of thesealing ring 42, that is to say in the sealing area. Thesealing rings encapsulated coil 10 and themetal housing 11 from passing on further into the connecting area 21 (see FIG. 1), and leading to corrosion there. - The
screw 31 is provided with aninternal thread 45, which is accessible from its head end. This is used for attachment of thehousing 20, which is illustrated schematically in FIG. 1, of the connecting plug. Thescrew 31 is thus used not only for connection of the contact lug 18 (which is associated with the protective ground conductor connection) to themetal housing 11, but also for attaching the connecting plug to theplug cap 17 of the encapsulatedcoil 10. - FIG. 3 shows a section, corresponding to FIG. 2, through the magnet coil arrangement in the area of the
plug cap 17. While thecontact lug 18 and thetubular metal part 36 are separate components in FIG. 2, these two components are combined in FIG. 3 to form acommon component 48 with acontact lug 18′ and atubular section 36′. The rest of its details correspond to those shown in FIGS. 2 and 3. The configuration of the contact lug and tubular metal part as one component reduces the number of individual parts. Furthermore, thecomponent 48 can be handled more easily than two separate individual parts. This simplifies the process of assembly of the magnet coil arrangement. Thecomponent 48 can be produced at low cost as a deep-drawn or thermoformed part.
